TiXmlDocument doc("example.xml"); if (doc.LoadFile()) { TiXmlElement* root = doc.FirstChildElement("root"); if (root && root->NoChildren()) { // Do something with the root element that has no children } }
TiXmlElement* parent = ...; while (!parent->NoChildren()) { parent->RemoveChild(parent->FirstChild()); }In this example, we have an element `parent` that we want to remove all child elements from. We use a `while` loop to repeatedly call `RemoveChild()` on the first child element until there are no more children left. Overall, TiXmlElement NoChildren() is a useful member function for working with XML documents in C++, and is part of the TinyXML-2 library.
